MHT CET Physics question
A source of sound S is moving with a velocity 50 m/s towards a stationary observer. The observer measures the frequency of the source as 1000 Hz. What will be the apparent frequency of the source when it is moving away from the observer after crossing him? The velocity of sound in the medium is 350 m/s
Answer: (A)
Solution
The true frequency is Hz, and receding it becomes Hz; 857 Hz
